what you eat/are

"tell me what you eat, and i will tell you who you are" is a well-worn quote from one Jean Anthelme Brillat-Savarin, and it is frequently used in similarly well-worn (read in both examples herein: overused) jokes along the lines of, to paraphrase internet parlance, "hahahaha i eat ass im an ass then hahahahaha." the original quote was meant to suggest that one's cuisine, taste, and food consumption, says much about them and who they are and where they come from. given, however, the rapidly ascendant meat heavy western diet now exploding in popularity in places like China, and given that the potato is also slowly pushing out rice as the global food staple, given that it is cheaper on a per calorie basis, one might be apt to conclude that, in a few hundred years, one will not have to ask what one eats, for we will all be, quite simply, meat and potatoes.
